Perpignan Cathedral construction was begun in 1324 by King Sancho of Majorca, and later finished in the 15th century. It replaced the Cathedral of Elna, and therefore the church was at first the seat of the Bishop of Elne, and then, from 1602, of the Bishop of Perpignan.
The cathedral was built in the Catalan Gothic style, because of its association with the Kingdom of Majorca. It has a wide nave (80 meters long, 18 m wide, and 26 m tall) made of seven cross-vaults, and features a short transept and apse, whose vault features seven keys.
The cathedral's western façade was never finished. When being restored in the 19th and 20th centuries, the Gothic window of the façade was rebuilt, as it had previously been substituted by a simple rectangular opening. The façade also features a portico and clock-tower, which date from the 18th century.
References:Ehrenbreitstein Fortress was built as the backbone of the regional fortification system, Festung Koblenz, by Prussia between 1817 and 1832 and guarded the middle Rhine region, an area that had been invaded by French troops repeatedly before. The fortress was never attacked.
Early fortifications at the site can be dated back to about 1000 BC. At about AD 1000 Ehrenbert erected a castle. The Archbishops of Trier expanded it with a supporting castle Burg Helferstein and guarded the Holy Tunic in it from 1657 to 1794. Successive Archbishops used the castle's strategic importance to barter between contending powers; thus in 1672 at the outset of war between France and Germany the Archbishop refused requests both from the envoys of Louis XIV and from Brandenburg's Ambassador, Christoph Caspar von Blumenthal, to permit the passage of troops across the Rhine.
